Функции

avcodec_find_encoder()

AVCodec* avcodec_find_encoder

(

enum AVCodecID

id

)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>

Find a registered encoder with a matching codec ID.

Аргументы

id	AVCodecID of the requested encoder

Возвращает

An encoder if one was found, NULL otherwise.

avcodec_find_encoder_by_name()

AVCodec* avcodec_find_encoder_by_name

(

const char *

name

)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>

Find a registered encoder with the specified name.

Аргументы

name	name of the requested encoder

Возвращает

An encoder if one was found, NULL otherwise.

avcodec_encode_audio2()

attribute_deprecated int avcodec_encode_audio2	(	AVCodecContext *	avctx,
		AVPacket *	avpkt,
		const AVFrame *	frame,
		int *	got_packet_ptr
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>

Encode a frame of audio.

Takes input samples from frame and writes the next output packet, if available, to avpkt. The output packet does not necessarily contain data for the most recent frame, as encoders can delay, split, and combine input frames internally as needed.

Аргументы

avctx

codec context

avpkt

output AVPacket. The user can supply an output buffer by setting avpkt->data and avpkt->size prior to calling the function, but if the size of the user-provided data is not large enough, encoding will fail. If avpkt->data and avpkt->size are set, avpkt->destruct must also be set. All other AVPacket fields will be reset by the encoder using av_init_packet(). If avpkt->data is NULL, the encoder will allocate it. The encoder will set avpkt->size to the size of the output packet.

If this function fails or produces no output, avpkt will be freed using av_packet_unref().

Аргументы

[in]	frame	AVFrame containing the raw audio data to be encoded. May be NULL when flushing an encoder that has the AV_CODEC_CAP_DELAY capability set. If AV_CODEC_CAP_VARIABLE_FRAME_SIZE is set, then each frame can have any number of samples. If it is not set, frame->nb_samples must be equal to avctx->frame_size for all frames except the last. The final frame may be smaller than avctx->frame_size.
[out]	got_packet_ptr	This field is set to 1 by libavcodec if the output packet is non-empty, and to 0 if it is empty. If the function returns an error, the packet can be assumed to be invalid, and the value of got_packet_ptr is undefined and should not be used.

Возвращает

0 on success, negative error code on failure

Уст.:

use avcodec_send_frame()/avcodec_receive_packet() instead

avcodec_encode_video2()

attribute_deprecated int avcodec_encode_video2	(	AVCodecContext *	avctx,
		AVPacket *	avpkt,
		const AVFrame *	frame,
		int *	got_packet_ptr
	)

#include <C:/git/world-of-might-and-magic/lib/win32/x86/ffmpeg-4.2.2/include/libavcodec/avcodec.h>

Encode a frame of video.

Takes input raw video data from frame and writes the next output packet, if available, to avpkt. The output packet does not necessarily contain data for the most recent frame, as encoders can delay and reorder input frames internally as needed.

avpkt

output AVPacket. The user can supply an output buffer by setting avpkt->data and avpkt->size prior to calling the function, but if the size of the user-provided data is not large enough, encoding will fail. All other AVPacket fields will be reset by the encoder using av_init_packet(). If avpkt->data is NULL, the encoder will allocate it. The encoder will set avpkt->size to the size of the output packet. The returned data (if any) belongs to the caller, he is responsible for freeing it.

If this function fails or produces no output, avpkt will be freed using av_packet_unref().
